What is wrong with sanding wood too fine?

If wood gets over-sanded in one spot, it starts to become uneven, with a distorted sort of appearance. This can happen to even the most experienced woodworker. Usually this starts simply by attempting to sand out a discoloration, defect, scratch or gouge.

What is the fine for sanding wood before finishing?

Hardwoods such as maple and oak: start with #120 and finish-sand no finer than #180 (for water base stains) and #150 grit for oil base stains. Do not over sand or you may seal the wood so much that it will not take a finish.

Can you sand too fine for stain?

Sanding more coarsely will allow more stain to remain on the surface. However, sanding too coarsely may result in visible sanding scratches as the pigment lodges in the scratch pattern. Most soft woods don’t need to be sanded any finer than 220 grit.

Is sanding important in finishing?

Surface Preparation Sanding is one of the most important steps in wood finishing. A thorough sanding is often what separates acceptable results from beautiful results. Start with a medium grade of sandpaper (e.g. #120) and gradually work your way to a finer grade (e.g. #220).

What to know when sanding wood for finish?

Use caution when sanding individual pieces to avoid rounding over crisp edges that may form gaps when joined and glued. Whether the project is a ready to finish piece of furniture, a freshly stripped old antique, a kit that needs assembly, now is the time to make minor repairs and do the finish sanding.

Can you close the pores in wood by sanding with too fine a.?

I think this claim makes no sense. But it is true that sanding to finer and finer grits limits the amount of color a stain imparts to the wood, after you wipe off the excess. Is there maybe a better explanation for this, one that is actually quite obvious?

What kind of sand paper do you use to finish wood?

In general, red garnet paper is used primarily for hand sanding. Grey to white aluminum oxide is used for either hand or power sanding; black silicon carbide is the abrasive of choice for very fine sanding in the woodworking field. Coarse sandpapers below 100 grit, are rarely used for fine furniture finishing.

Why does sanding with finer grits make scratches?

It seems to me that the simpler explanation is that finer grit sandpapers create finer scratches so less stain color will remain after you wipe off the excess stain. This is easily testable simply by sanding to different grits, applying stain, then wiping off the excess and compare.
